What concentration of oxygen should be used In Resuscitation?

During resuscitation, it is recommended to use 100% concentration of oxygen. This is because the primary objective of resuscitation is to quickly and effectively restore tissue oxygenation and reverse hypoxemia, which is the deficiency of oxygen in the blood.

100% oxygen is the most concentrated form of oxygen that can be delivered and is essential in critical situations where immediate oxygenation is needed. It allows for the rapid increase in the partial pressure of oxygen in the lungs and subsequently in the arterial blood, resulting in improved oxygen delivery to vital organs and tissues.

By providing 100% oxygen, the amount of oxygen carried in the blood is maximized, ensuring that the body's oxygen demands are met. This is particularly crucial during resuscitation efforts when the goal is to restore normal physiological function and prevent any further deterioration of the patient's condition.

However, it is worth noting that while 100% oxygen is typically used during resuscitation, there might be certain situations or underlying medical conditions where lower oxygen concentrations may be considered, such as in patients with chronic obstructive pulmonary disease (COPD) or during certain phases of neonatal resuscitation. In these specific scenarios, healthcare professionals will adjust the oxygen concentration based on the patient's individual needs and response.
